When speaking of history of American politics

When speaking of history of American politics, it is easy to go deeper into the field of religion. Christianity has a given place as the norm in many politicians’ speeches, although some politicians never forget to mention that U.S.A. is a nation of many different religions (not to mention some minorities, including others).
Almost all the speeches of American presidents show that their language can easily be associated with the Christian faith. What is important, the references to God, God’s will and God’s promises, cannot solely be tied to Christianity, because these references are appropriate to various faiths that recognize the existence of one God.
